→Graphical conventions 画图公约
Alternative conventions to node–link diagrams include adjacency representations such as circle packings, in which vertices are represented by disjoint regions in the plane and edges are represented by adjacencies between regions; intersection representations in which vertices are represented by non-disjoint geometric objects and edges are represented by their intersections; visibility representations in which vertices are represented by regions in the plane and edges are represented by regions that have an unobstructed line of sight to each other; confluent drawings, in which edges are represented as smooth curves within mathematical train tracks; fabrics, in which nodes are represented as horizontal lines and edges as vertical lines; and visualizations of the adjacency matrix of the graph.

节点链接图可被其他画图方式替代，包括邻接表示法，如'''<font color="#ff8000">圆填充 Circle Packings</font>'''，其中顶点表示为平面上不相交的区域，边表示为区域之间的邻接; '''<font color="#ff8000">交点表示 Intersection representations</font>'''，其中顶点由非相交的几何对象表示，而边由其交点表示；可见性：其中顶点由平面中的区域表示，边由彼此无障碍视线的区域表示; 汇流图，其中边表示为数学轨迹上的光滑曲线; 织物，其中顶点表示为水平线，边表示为垂直线; 以及图形'''<font color="#ff8000">邻接矩阵 Adjiacency Matrix</font>'''的可视化结点。
